SOP: Supply Chain Risk Management (SCRM) Framework

Document ID: TR-SCRM-NIST-800-161
Effective Date: 2024-05-20
Version: 1.0.0
Review Cadence: Annual
Target Audience: Cybersecurity Operations, Procurement, Legal, and Executive Risk Committees

---

1. Executive Summary & Scope

This SOP establishes the operational cadence for implementing a Supply Chain Risk Management (SCRM) framework aligned with NIST SP 800-161 Rev. 1. The scope covers the end-to-end lifecycle of ICT supply chain procurement, integration, monitoring, and decommissioning. This document serves as the institutional blueprint to mitigate risks related to counterfeit components, malicious software injection, and vendor integrity.

2. Prerequisites & Tool Requirements

• Access: GRC (Governance, Risk, and Compliance) platform access (e.g., Archer, OneTrust, or equivalent).
• Certifications: Personnel must hold current C-SCRM awareness training or equivalent industry certifications (e.g., CISSP, CRISC).
• Documentation: Current Inventory of Assets (CMDB), Vendor Master List, and SBOM (Software Bill of Materials) repository access.
• Connectivity: VPN access to isolated sandbox environments for security software verification.

4. Step-by-Step Operational Procedure

Phase I: Identification & Scoping

• Conduct classification of supply chain elements based on criticality to business operations.
• Identify high-risk suppliers utilizing the NIST Tier 1/2/3 categorization.
• Map all Tier 1 suppliers and establish dependencies for Tier 2/3.

Phase II: Assessment & Verification

• Request and validate SBOMs for all third-party software components.
• Perform a NIST 800-161 control gap analysis on vendor security documentation.
• Execute hardware integrity validation (e.g., tamper-evident checks, serial verification).

Phase III: Risk Response

• Determine risk mitigation strategy (Accept, Avoid, Transfer, or Mitigate).
• Draft risk-remediation contractual clauses for legal review.
• Implement compensating controls for suppliers failing to meet NIST baseline standards.

Phase IV: Continuous Monitoring

• Initiate automated threat intelligence feed monitoring for supply chain indicators of compromise.
• Schedule quarterly reviews of vendor security health scores.
• Audit incident response logs from suppliers for documented breach disclosure.

6. Practical Troubleshooting Scenarios

Scenario A: Zero-Day Vulnerability Identified in Critical Tier 1 Vendor Component

• Corrective Action: Immediately trigger the "Containment Protocol." Isolate the affected asset from the production network. Notify the vendor to request a patch timeline. If no patch exists, disable the specific feature or switch to a secondary pre-validated supplier.

Scenario B: Vendor Fails to Provide Updated SBOM during Annual Review

• Corrective Action: Escalate to Procurement/Legal. Initiate a formal "Notice of Non-Compliance." Freeze new deployments of that vendor’s services until the documentation is submitted and validated by the Operations Architect.

Scenario C: Discrepancy Found in Hardware Physical Inspection (Counterfeit Suspected)

• Corrective Action: Quarantine the physical asset immediately in an ESD-safe, secured evidence locker. Document the discrepancy with serial number photographs. Notify the vendor and the National Intellectual Property Rights Coordination Center (IPR Center).
